[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0022] Example 1: See Figures 1 to 3 As shown, a cable connector comprises a body 1, a limiting sleeve 2 for limiting the cable is provided at the right end of the body, a plug-in terminal is provided inside the left end of the body, two groups of limiting protrusions 3 are symmetrically provided on the outer edge surface of the right end of the body, two groups of limiting grooves 4 are symmetrically provided on the inner wall of the limiting sleeve, the front end of the limiting groove is connected with the left side surface of the limiting sleeve, the limiting sleeve is inserted on the right end of the body, each group of the limiting protrusions is inserted in a group of the limiting grooves, and the limiting sleeve is rotated to clamp the limiting protrusions at the right end of the limiting groove, and the limiting protrusions and the limiting grooves lock the body and the limiting sleeve together.

[0023] In this embodiment, a screw sleeve is provided on the left side of the body for connecting with another set of connectors, a plug connector is provided inside the left side of the body for plugging and matching with another set of connectors, and the right end is used to connect the cable, the end of the cable is inserted into the body, and the cable is locked in the body by the limit sleeve. In the previous structure, the cable is locked by the screw sleeve, which has low installation efficiency and slow speed. Therefore, in this embodiment, a limiting protrusion is provided on the outside of the main body and a limiting groove is provided inside the limiting sleeve. In this way, during installation, the limiting sleeve is directly sleeved on the outside of the cable, and then the left side of the limiting sleeve is first sleeved on the outside of the right end of the main body, so that the limiting protrusion is inserted into the limiting groove, and then the limiting sleeve is rotated so that the limiting protrusion is inserted into the limiting groove, and the limiting sleeve and the main body are locked by using the limiting protrusion and the limiting groove. In this way, the installation efficiency is high, and the limiting sleeve only needs to be rotated a certain angle to complete the locking and limiting. The rotation angle will be less than 180 degrees, the installation efficiency is high, and the disassembly speed is also fast. At the same time, after the installation is completed, the locking quality of the cable and the connector can also be guaranteed.

[0024] See also Figure 2 , 3 As shown, the limit groove includes a transverse groove 5, an oblique groove 6 and a vertical groove 7 which are interconnected. The transverse groove is arranged perpendicular to the vertical groove, and the transverse groove is arranged parallel to the axis of the limit sleeve. The front end of the transverse groove is connected to the left side of the limit sleeve, the left side of the oblique groove is connected to the right side of the transverse groove, the right end of the oblique groove is connected to one end of the vertical groove, and an arc groove 8 is provided on the left side of the other end of the vertical groove, and the oblique groove is inclined from left to right along the clockwise direction.

[0025] When the limiting sleeve and the body are locked, the limiting protrusion is clamped in the arc groove at the end of the vertical groove, and the limiting protrusion is arranged away from the right end of the inclined groove.

[0026] When the locking cam is in the locked position, the locking cam will move to the left, and when the locking cam moves to the right end of the locking cam, the locking cam will move to the right, and the locking cam will move to the left, and the locking cam will move to the right, so that the locking cam will be locked in the locking cam. In this embodiment, due to the setting of the vertical groove, the limiting protrusion is limited by the vertical groove, so that when the limiting sleeve and the body are subjected to opposite forces, the limiting sleeve and the body will not separate, which can ensure the firmness of the locking, and the locking installation efficiency is high and the quality is good. At the same time, two sets of limiting grooves are used, so that the rotation angle of the limiting sleeve is less than 180 degrees to achieve the locking installation of the limiting sleeve and the body, which is efficient, and the disassembly can be achieved by rotating in the opposite direction when disassembling, and the quick disassembly work can be achieved.

[0027] The setting of the arc groove requires a greater force to rotate the limit sleeve, so that the deformation locking force of the limit sleeve can be offset to allow the limit protrusion to rotate into the vertical groove and the inclined groove.

[0028] The inner wall of the right end of the limiting sleeve is provided with a limiting convex ring 9, and the left side of the limiting convex ring abuts against the right side of the body. The setting of the limiting convex ring can lock and limit the sealing sleeve of the cable in the body to prevent the sealing sleeve from detaching from the body.

[0029] See also Figure 1 , 2 As shown, an annular protrusion 10 is provided on the middle outer edge surface of the main body, the left side surface of the limiting sleeve abuts against the right side surface of the annular protrusion, and two groups of limiting planes 11 are symmetrically provided on the outer edge surface of the annular protrusion, the two groups of limiting planes are arranged parallel to each other, and the limiting planes are arranged parallel to the axis of the main body; two groups of installation planes 12 are symmetrically provided on the outer edge surface of the limiting sleeve, the two groups of installation planes are arranged parallel to each other, and the installation planes are arranged parallel to the axis of the limiting sleeve.

[0030] In this embodiment, under normal circumstances, after the limiting protrusion touches the right end of the inclined groove, the left side of the limiting sleeve will contact the right side of the annular protrusion, so that it cannot continue to move to the left, so that the locking and limiting of the limiting sleeve can be completed. Among them, if the limiting sleeve is subjected to tension at this time, the limiting sleeve may rotate in the opposite direction, so that the limiting sleeve and the limiting protrusion are separated. Therefore, in order to prevent the limiting sleeve from loosening, the limiting sleeve is continuously rotated so that the limiting protrusion is separated from the inclined groove and inserted into the vertical groove, which will also squeeze the left side of the limiting sleeve. In this way, when the limiting sleeve is subjected to tension, it will be stuck in the vertical groove. The limiting sleeve must be rotated in the opposite direction by force to make the limiting protrusion separate from the vertical groove into the inclined groove, and then gradually loosen to complete the removal of the limiting sleeve, so that the firmness and stability of the connection between the limiting sleeve and the body can be ensured.

[0031] At the same time, in order to facilitate the connection between the limit sleeve and the main body and ensure that the limit sleeve can be easily rotated and connected to the main body for installation, a limit plane and an installation plane are set to facilitate the use of tools to limit the main body and the limit sleeve, ensuring that during the locking process, the limit sleeve rotates and the main body does not rotate, thereby facilitating the installation or disassembly of the limit sleeve and the main body.

[0032] See also Figure 1 As shown, two groups of arc-shaped slots 13 are symmetrically arranged on the outer edge surface of the annular protrusion, and each group of the arc-shaped slots is arranged between the two groups of the limiting planes. In this embodiment, the arc-shaped slots are arranged for installing logo parts, so that after the connector is produced, when different manufacturers purchase it, they can just insert their own logo parts into the corresponding arc-shaped slots, without the need for laser coding, which is more efficient and more cost-effective.

[0033] See also Figure 1 As shown, the left and right sides of the outer edge of the arc-shaped slot are respectively provided with inwardly extending limiting convex strips 14, and the two groups of limiting convex strips are arranged oppositely, and the length of the limiting convex strips is less than the length of the arc-shaped slot. The setting of the limiting convex strips is used to limit the position of the logo component so that it will not fall out of the arc-shaped slot when in use.

[0034] Wherein, the oblique groove and the vertical groove are communicated with the outer wall of the limiting sleeve.

[0035] A plastic protective sleeve 15 is sleeved on the left outer edge surface of the limiting sleeve, and the limiting groove is arranged inside the plastic protective sleeve. In this embodiment, the plastic protective sleeve is arranged to provide a certain protection to the outside of the limiting sleeve, and the protective sleeve made of plastic can have a certain elasticity, so that after the plastic protective sleeve contacts the annular protrusion first, when the limiting sleeve is continuously rotated to lock the limiting sleeve with the body, a certain deformation space is given, and the elasticity of the plastic protective sleeve can also be used to give the limiting sleeve a rightward thrust, so that the limiting protrusion will be firmly stuck in the vertical groove to ensure the stability of the limit.
